The requirements of cold regenerator in road construction are very high. When it wants to reach its structural life, it will produce deep cracks, pits and bags, resulting in serious decline of road performance. As an economical road maintenance and reconstruction method, the main advantage of in-situ cold regeneration is that the existing pavement is strengthened by 100% using old materials, and the foundation needs to be strengthened. Secondly, it has the advantages of short construction period and small interference to public transportation. Moreover, compared with other maintenance methods, the cost of in-situ cold regeneration will be greatly reduced, So as to save more manpower and material resources!

冷再生機(jī)出租的時(shí)候，都是具有針對(duì)性的，還一直采用修新路用的傳統(tǒng)設(shè)備，以傳統(tǒng)的重建方式進(jìn)行。盡管這種方法可以保證質(zhì)量，但顯得過(guò)于笨重、工期過(guò)長(zhǎng)，特別是不能不斷交施工。更由于不能充分利用現(xiàn)有路面材料，不僅成本很高，也不。由于及經(jīng)濟(jì)的原因，盡可能多地利用現(xiàn)有路面鋪層材料進(jìn)行道路維修。

When the cold regenerator is rented, it is targeted, and the traditional equipment for road repair has been used in the traditional way of reconstruction. Although this method can ensure the quality, it is too cumbersome and the construction period is too long, especially it can not be handed over continuously. Moreover, due to the inability to make full use of the existing pavement materials, it is not only costly, but also environmentally friendly. Due to environmental protection and economic reasons, the existing pavement paving materials shall be used as much as possible for road maintenance.

冷再生機(jī)租賃的時(shí)候，是根據(jù)現(xiàn)有路面銑刨到確定的深度，以便獲得現(xiàn)有鋪層材料。然后，通過(guò)加入粘結(jié)劑對(duì)這些材料進(jìn)行再生處理，從而獲得一個(gè)得到加強(qiáng)的新鋪層。整個(gè)再生過(guò)程是一個(gè)一次性的過(guò)程?，F(xiàn)在，已經(jīng)有成熟的集現(xiàn)代工程機(jī)械新技術(shù)于一身的再生機(jī)械，現(xiàn)在，就地冷再生作為一種舊路維修改造方法，已經(jīng)在世界上許多得到廣泛承認(rèn)。這一工藝適用于維修或升級(jí)改造從無(wú)鋪面的礫石路，到承受重負(fù)荷的干線公路的大范圍的道路。

When the cold regenerator is leased, it is first milled to the determined depth according to the existing pavement in order to obtain the existing paving material. Then, these materials are regenerated by adding binder, so as to obtain a new reinforced layer. The whole regeneration process is a one-off process. Now, there are mature regeneration machines integrating new technologies of modern construction machinery. Now, as a method of old road maintenance and reconstruction, in-situ cold regeneration has been widely recognized in many countries in the world. This process is suitable for repairing or upgrading a wide range of roads from unpaved gravel roads to heavy-duty trunk roads.
